Changelog¶ ↑

2.0.0 / 2014-05-09¶ ↑

Compatibility notes:

ActionView helpers now must be required explicitly: `require “loofah/helpers”`
Support for Ruby 1.8.7 and prior has been dropped

Enhancements:

HTML5 whitelist allows the following …
- tags: `article`, `aside`, `bdi`, `bdo`, `canvas`, `command`, `datalist`, `details`, `figcaption`, `figure`, `footer`, `header`, `mark`, `meter`, `nav`, `output`, `section`, `summary`, `time`
- attributes: `data-*` (Thanks, Rafael Franca!)
- URI attributes: `poster` and `preload`
Addition of the `:unprintable` scrubber to remove unprintable characters from text nodes. #65 (Thanks, Matt Swanson!)

HTML5 sanitizers now remove attributes without values. (Thanks, Kasper Timm Hansen!)

Bug fixes:

HTML5 sanitizers' CSS keyword check now actually works (broken in v2.0). Additional regression tests added. (Thanks, Kasper Timm Hansen!)
HTML5 sanitizers now allow negative arguments to CSS. #64 (Thanks, Jon Calhoun!)

1.2.1 (2012-04-14)¶ ↑

Declaring encoding in html5/scrub.rb. Without this, use of the ruby -KU option would cause havoc. (#32)

1.2.0 (2011-08-08)¶ ↑

Enhancements:

Loofah::Helpers#sanitize_css is a replacement for Rails's built-in sanitize_css helper.
Improving ActionView integration.

1.1.0 (2011-08-08)¶ ↑

Enhancements:

Additional HTML5lib whitelist elements (from html5lib 1524:80b5efe26230). Up to date with HTML5lib ruby code as of 1723:7ee6a0331856.
Whitelists (which are not part of the public API) are now Sets (were previously Arrays).
Don't explode when encountering UTF-8 URIs. (#25, #29)

1.0.0 (2010-10-26)¶ ↑

Notes:

Moved ActiveRecord functionality into `loofah-activerecord` gem.
Removed DEPRECATIONS.rdoc documenting 0.3.0 API changes.

0.4.7 (2010-03-09)¶ ↑

Enhancements:

New methods Loofah::TextBehavior#to_text and Loofah::TextBehavior#to_text do the right thing with whitespace. Note that these methods are significantly slower than text. GH #12
Loofah::Elements::BLOCK_LEVEL contains a canonical list of HTML4 block-level4 elements.
Loofah::TextBehavior#text and Loofah::TextBehavior#text will return unescaped HTML entities by passing :encode_special_chars => false.

0.4.4, 0.4.5, 0.4.6 (2010-02-01)¶ ↑

Enhancements:

Loofah::TextBehavior#text and Loofah::TextBehavior#text now escape HTML entities.

Bug fixes:

Loofah::XssFoliate was not properly escaping HTML entities when implicitly scrubbing a string attribute. GH #17

0.4.3 (2010-01-29)¶ ↑

Enhancements:

All built-in scrubbers are accepted by ActiveRecord::Base.xss_foliate
Loofah::XssFoliate.xss_foliate_all_models replaces use of the constant LOOFAH_XSS_FOLIATE_ALL_MODELS

Miscellaneous:

Modified documentation for bootstrapping XssFoliate in a Rails app, since the use of Bundler breaks the previously-documented method. To be safe, always use an initializer file.

0.4.2 (2010-01-22)¶ ↑

Enhancements:

Implemented Node#scrub! for scrubbing subtrees.
Implemented NodeSet#scrub! for scrubbing a set of subtrees.
Document.text now only serializes <body> contents (ignores <head>)
